Issue with AC charging/New CCU fitted (Phase One SE LR)

[Talky Toaster]

Fingers crossed!

Well, seems it wants to charge at every opportunity now and not wait for my charging schedule . I knew I should have chalked a pentangle round the thing.

Hello, unfortunately yet another moan about MG4 not charging AC. My MG4 has been with DriveMG, Hull since 22/12/2023 who seemed unable to diagnose the fault with the car, despite applying 5 software updates that they believed would resolve the issue. As some of you will know, software updates are not resolving the fault(s). I contacted MG customer service tech. who told me they had instructed DriveMG, Hull to carry out various tests, one after the other, they appear to have a very specific process in this regard. Their last email told me it could be one of two faults, but did not know what potential faults. I again rang the dealer Monday 29/01, whose customer service requires an update (intentional pun) specifically with regard to communication, who told me the parts had arrived with them. Am now awaiting a phone call from DriveMG, Hull telling me my car is fixed and what the faults were. They can then have back the petrol loan car I've been using.

Sounds like another CCU failure and replacement. Is yours an early (no rear wiper) long range SE or Trophy?

Yes it is, long range Trophy. Further to me emailing the dealers customer service team, I have received a phone call from the dealer explaining the faults with my car are the CCU & preconditioning unit ie. it pre- heats the battery bringing it up to temperature. This is required in order for the car's system to accept & charge the battery. The latter part is on a ship somewhere & due to embark to the dealer next Wednesday. The CCU has been fitted.

Ac charging at home stops after 2 minutes or so on both type 2 (pod point solo) and granny plug charging - scheduling off, charge up to 100% set etc etc .

Just been down to the the DC charging station and no problem getting to near 100%.

Any ideas ?

TIA

Sounds like you have a phase 1 car, have a read through this thread, your not alone.

Will probably need a new CCU, contact your dealer.

Edit: Originally, I thought I had an issue with my Zappi not being able to charge the car, but after testing other AC charging points (cutting out after fifteen minutes or less) and contacting the dealer, I eventually found out it was an issue with the car, namely the charge control unit, which...

Unfortunately, it sounds exactly like the problem I and others in the thread I started have been experiencing. They’ll try to “fix” it first with software updates, but make sure the technician thoroughly checks it otherwise you’ll be going back and forth to the dealers. I’m currently waiting on delivery of a new CCU and charging on DC only at present.

I take it was a used car & doesn’t have a rear window wiper ?

Mods @Rolfe think you might want to merge this into the Zappi thread!

 

[siteguru]

Might be worth first waiting for @Silent running to confirm that theirs is indeed a Phase 1 car (without the rear wiper).

I guess to be sure you're right - what do you reckon the odds are???? 95%

 

[Rolfe]

I've merged this in with the existing thread on the issue, because it sounds like exactly the same thing. @Silent running, have a read up-thread and you'll find out what is fixing this for other people.

If they have a Phase 2 model then I think that would be the first one with this issue? That's why I thought it premature to merge the threads at this time.

Since the problem takes months to occur, it could easily affect Phase 2 cars we just haven't hit it yet, or it could be limited to Phase 1 chargers or even a specific batch.

I suspect the Phase 2 models (Trophy, XPower and SE LR) have the same charger as the Phase 1 and 2 SE models - i.e. 6.6kW single phase ... if true then this unit has had 18 months or so for such an issue to develop.

You are a very suspicious person

Just out of interest as I too have a Phase 1 Trophy.

Those who are definitely having or have had a new CCU fitted:
1. What was the build date of your Trophy?
2. Which home charger are you using?
3. Which supplier and tariff are you on?
